When u need one u will never find one

They always spawn in packs of 5 so make sure to leave no trilobite unfound

When I was on like level 20 in single player i used to find these guys everywhere, and i thought they were only useful for a handful of chitin. Now I’m on level 88 and i actually NEED black and silicia pearls and oil I haven’t seen one in months.

You can find these at herbivore Island around the edges in the water!

These animals are ancient! And are believed( by some) to be related to the horseshoe crab. They look alike, in some ways! Trilobites were one of the first massive sea animals around ( back then, these were considered massive, due to life still getting the hang of making non- micro sized creatures.) but eventually went extinct by an apex predator that adapted to break their rough armor, and sadly that was the end.

They spawn near herb island if you wanted to know

Kill on site they give chitin oil and pearls when you need them they disappear

Use a hatchet or megatherium to harvest for max silica pearls and oil. Gives about a stack of chitin with a primitive metal hatchet and loads with the mega.

Keep the pearls. You'll thank me later.

All you need is a spear or pike and you have a good source of silica pearls,black pearls,and chitin st low levels.
